Now the latest on the search for flight 370. More debris spotted by satellite this morning but bad weather has grounded planes again. ABC's David Kerley has been following this from the start and is with us again this morning. Good morning, David. Good morning, robin. Even more evidence of something on the surface of the Indian ocean and this latest image is near where those four other images came and show potential debris but still not one piece has been picked up and the weather is not cooperating. This is the image the Thai government released showing what it says are 300 floating objects taken Monday in an area close to some of the other images but still no vessel in that area has been able to pick up any actual debris. And this is part of the reason why. The satellites don't show this, the rough south Indian ocean, churning kurpss and today the weather was so bad with the storm over the area, the Australians called off the air search until Friday. Finding debris will yield many clues about how the aircraft may have hit the water and experts can trace back the currents to give a better location to start towing this bat wing-shaped device through the water. On the end of nearly 40,000 feet of cable it will get close to the bottom of the ocean floor to listen for those black boxes. The signal comes up the cable and it's received by here. Operators will sit in front of this screen listening for any indication that the pinger is heard. The pinger underwater sounds like this. Reporter: The head of the FBI says his experts have just about finished investigating the hard drive that was part of the pilot's home flight simulator. The captain and co-pilot remain part of the investigation into why the jetliner with 239 on board dramatically veered off course and flew more than seven hours into one of the remotest places on Earth. Now, there is some good news. The weather is going to improve significantly into the weekend. Winds and waves will calm a bit giving the vessels in this area possibly their best chance ever to actually find some of this wreckage.
